infinite solutions
Step-by-step explanation:
<h3>
Answer: Choice B. x = 4 and x = 3</h3>
Work Shown:
x^2 - 7x = -12
x^2 - 7x + 12 = 0
(x - 3)(x - 4) = 0 ... see note below
x - 3 = 0 or x - 4 = 0
x = 3 or x = 4
Note: we're looking for two numbers that multiply to 12 and add to -7. Those two numbers are -3 and -4, so that's where the factorization (x-3)(x-4) comes in. After this step, you set each factor equal to zero and solve for x.
The equipment of a straight line is 7
Hey there! :)
If the width is 10 ft and the farmer wants the length to be 3x the width:
Length = 3w
W = 10
10 × 3 = 30
The width is 10 ft and the length is 30 ft.
Remember: You have to find the perimeter
Perimeter = 2l + 2w
l = 30
30 × 2 = 60
w = 10
10 × 2 = 20
60 + 20 = 80
Your answer is 80 ft of fencing
Hope this helps :)
